溶胶-凝胶法制备陶瓷膜研究进展
|
摘要
膜处理技术被誉为"世界范围内的水处理技术"。膜处理过程中约80%的膜为无机陶瓷膜。无机陶瓷膜因其具有化学稳定性好、机械强度大、耐酸碱、耐高温等优点,在复杂水体处理中具有显著技术优势。陶瓷膜层的制备方法主要有水热法、颗粒浸涂法、化学气相沉积法、模板合成法、溶胶-凝胶法等。溶胶-凝胶法制备陶瓷膜是国外研究最多的一种重要方法。对陶瓷膜和溶胶-凝胶法的概念、原理等进行介绍和阐述,在此基础上系统归纳了采用溶胶-凝胶法制备二氧化硅陶瓷膜、三氧化二铝陶瓷膜和三氧化二铝-二氧化硅复合陶瓷膜的研究进展、应用领域及存在问题,最后展望了陶瓷膜发展趋势。
Membrane treatment technology is known as the "worldwide water treatment technology".About 80% of the membranes are inorganic ceramic membranes.Inorganic ceramic membrane has obvious technical advantages in complex water treatment because of its good chemical stability,high mechanical strength,better acid and alkali resistance,high temperature resistance and so on.The main preparation methods of ceramic film are hydrothermal method,particle immersion method,chemical vapor deposition method, template synthesis method,sol-gel method and so on.Among them,sol-gel method is one of the most important methods for the preparation of ceramic membranes.The concept and principle of ceramic membrane and sol-gel method were introduced and expounded.On the basis of this,the progress in the preparation of SiO_2 ceramic membrane,Al_2O_3 ceramic membrane and Al_2O_3-SiO_2 composite ceramic membrane by sol-gel method was systematically summarized.Finally,the development trend of ceramic membrane was proposed.
